Question

我正在开发Android BLE应用程序。我面临一个问题：-每次尝试连接设备BluetoothProfile.STATE_DISCONNECTED的应用程序都在调用时。它在5,6次尝试连接中连接1次，一旦连接，它将在接下来的4,5次调用BluetoothProfile.STATE_DISCONNECTED。我在断开连接时关闭了GATT连接。这是断开连接的代码

public void disconnect() {
    if (mBluetoothAdapter == null || mBluetoothGatt == null) {
        Log.w(TAG, "BluetoothAdapter not initialized");
        return;
    }
    mBluetoothGatt.disconnect();
}

/**
 * After using a given BLE device, the app must call this method to ensure
 * resources are released properly.
 */

public void close() {
    if (mBluetoothGatt == null) {
        return;
    }
    mBluetoothGatt.close();
    mBluetoothGatt = null;
}

我在：

中调用这些方法

else if (newState == BluetoothProfile.STATE_DISCONNECTED) {
            mConnectionState = STATE_DISCONNECTED;
            disconnect();
            close();
            Utility.dismissProgress();


            Log.i(TAG, "Disconnected from GATT server.");
            Intent intent = new Intent(ACTION_GATT_DISCONNECTED);
            intent.putExtra("DISCONNECTED_DEVICE_ADDRESS", gatt.getDevice().getAddress());
            sendBroadcast(intent);
        }.

我需要每次都应该调用connect。

您正在使用哪个AN设备？

if (newState == BluetoothProfile.STATE_DISCONNECTED) {
            if (status!=133&&status!=62||disconnectCount>=2) { /*If more then 2 count gatt close process*/
                disconnectCount=0;
                setConnected(false);
                intentAction = MyUtils.ACTION_GATT_DISCONNECTED;
                if (getmBluetoothGatt() != null)
                    refreshDeviceCache(mBluetoothGatt);
                getmBluetoothGatt().close();
                setmBluetoothGatt(null);

            }else { /*reconnection goes here*/
                disconnectCount++;
                if (isConnected) {
                    disconnectDevice();
                }
                connectDevice(mDevice);
            }
         }

尝试一下可能会有帮助。

BLE（BluetoothGatt）连接一次后再次调用断开连接
